How come some electric banjos sound like banjos, and some don't?

[Driver Blues]

This is probably a more niche topic, but how come some electric banjos sound like a mic'ed banjo and some just sound like I'm playing an electric guitar tuned like it was a banjo?

The pickup/preamp/electronics. The strings aren't what makes a banjo sound like a banjo, so it takes more than piezo saddles to get that sound.

A piezo on the drum head will sound like a banjo.

It's probably up to the manufacturer. There's not a massive market for electric banjos that I know of, but I could see reasons to make then both ways.
